ABSTRACT:
In the described optical device a linear object element forms an image by two straight lines crossing each other at a specific angle. Thus it is possible to achieve a crosswise movement of the image point downstream of the optical device with only a single linear scanning movement upstream of the optical device. In particular it is possible to scan plane structures with a single scanning movement.
